The utility model solves its technical problem and takes following technical scheme to realize:
This pipe reducing bend pipe processing unit (plant), constitute by mainframe, workbench, movable platform, movable platform is promoted to carry out vertical lifting by the oil cylinder that is fixed in the frame upper end, is fixed with patrix and counterdie respectively at the lower surface of movable platform and the upper surface of workbench, it is characterized in that:
The surface of counterdie and patrix is shaped on the curved groove of reducing of mutual fastening respectively, being limited in patrix and the counterdie of the curved groove of the reducing of this patrix and counterdie than minor diameter one end, the curved groove of its reducing extend to the edge of patrix or counterdie than major diameter one end;
Also comprise the high pressure water injection pipe that a split is provided with, this high pressure water injection pipe is shaped on circular plug near the end position of delivery port, and this high-pressure water pipe is connected with water pump by pipeline.
And, be shaped on reference column at the lower surface of described patrix, be shaped on the locating hole that matches with this reference column at the upper surface of counterdie.
And, on the inwall than minor diameter one end of the curved groove of reducing that described counterdie was shaped on, be shaped on axial cylindricality shutoff.
Advantage of the present utility model and good effect are:
1. this pipe reducing bend pipe processing unit (plant) adopts high-pressure water pipe that the end of high-pressure coolant from equal-diameter elbow injected, equal-diameter elbow inside is under pressure and acts on and generation deformation, final and patrix, the curved groove inwall of reducing made on the counterdie fits, several seconds can be finished the tapering moulding of reducing bend pipe, this kind method has replaced the mode that adopts before copper sheet rolling and welding processing reducing bend pipe, can adopt equal-diameter elbow as blank, because equal-diameter elbow is easy to processing and manufacturing, therefore can save manufacturing procedure greatly, reduce production costs, and machining accuracy height, reducing elbow roundness after the moulding is good, need not to carry out once more integer.
2. the utility model scientific structure design is reasonable, has higher automatization level, employing is expanded to equal-diameter elbow and is made tapering, can carry out the processing of reducing bend pipe and precision height, good product quality, beautiful outline form viewpoint fast, is adapted to pipe musical instrument reducing bend pipe industrialized mass production.
